Estimates of output gaps continue to play a key role in assessments of the stance of business cycles. This paper uses three approaches to examine the historical record of output gap measurements and their use in surveillance within the IMF. Firstly, the historical record of global output gap...

We argue that in an economy with downward nominal wage rigidity, the output gap is negative on average. Because it is more difficult to cut wages than to increase them, firms reduce employment more during downturns than they increase employment during expansions. This is demonstrated in a simple...

Is the Mundell-Fleming trilemma alive and well? International co-movement of asset prices takes place alongside synchronized business cycles, complicating the identification of financial spillovers and assessments of monetary policy autonomy. A benchmark for interest rate comovement is to impose...

We provide a multidimensional characterization of monetary policy frameworks across three pillars: Independence and Accountability, Policy and Operational Strategy, and Communications (IAPOC). We construct the IAPOC index by analyzing central banks' laws and websites for 50 advanced economies,...

Chile offers an example of a country that has overcome the fear of floating by reducing balance sheet mismatches, enhancing financial market development, as well as improving monetary, fiscal, and political institutions, and strengthening policy credibility. Under the floating regime, Chile's...

We study the properties of the IMF-WEO estimates of real-time output gaps for countries in the euro area as well as the determinants of their revisions over 1994-2017. The analysis shows that staff typically saw economies as operating below their potential. In real time, output gaps tend to have...

This paper surveys three types of monetary arrangements. It considers how the choice of an exchange rate regime, the degree of central bank independence, or choice of currency unions or boards depends not only on economic considerations but also on political economy considerations. In economic...

We consider the optimality of various institutional arrangements for agencies that conduct macro-prudential regulation and monetary policy. When a central bank is in charge of price and financial stability, a new time inconsistency problem may arise. Ex-ante, the central bank chooses the...

This paper extends the analysis of central bank independence to a model in which there is more than one policymaker. It shows that the degree of central bank independence as generally defined in the existing theoretical literature is only one of the influences on macroeconomic performance. The...

Monetary independence is at the core of the macroeconomic policy trilemma stating that an independent monetary policy, a fixed exchange rate and free movement of capital cannot exist at the same time. This study examines the relationship between monetary autonomy and inflation dynamics in a...
